Bianchi - NEW Infinito 2026 - Shimano 105 Di2

 Bianchi - New Infinito 2026 - Shimano 105 Di2 Bike

The Bianchi Infinito 105 Di2 is the smart entry point into Bianchi's redesigned 2026 Infinito carbon endurance platform. At $4,200, this bike gives riders the same core frame story as the higher-end Infinito builds: a fully integrated carbon chassis and fork, a claimed 12-watt aerodynamic improvement over the previous Infinito, endurance-focused geometry, Countervail comfort technology, internal down tube storage, and clearance for tires up to 700x40. The difference is simple: this version pairs that premium frame with Shimano 105 Di2 electronic shifting, durable alloy wheels, and an honest price.

If you are searching for the best endurance road bike with electronic shifting, a comfortable carbon road bike for long rides, a road bike with 40 mm tire clearance, or a Bianchi Infinito 105 Di2 in Metallic Celeste / CK16 or Burgundy Red / White, this is the model built to answer that need. It is fast enough for group rides, comfortable enough for centuries, practical enough for rough pavement, and versatile enough for riders who want one premium road bike that can handle more than perfect asphalt.

The Infinito 105 Di2 is available in two distinctive colorways: Metallic Celeste / CK16, a modern two-tone interpretation of Bianchi's signature color, and Burgundy Red / White, a striking finish that stands apart in a category often dominated by black carbon bikes. Both colorways are available across the full imported size run from 47cm to 61cm.

Why Buy the Bianchi Infinito 105 Di2?

Buy this bike if you want the new Bianchi Infinito frame platform without paying for components you may upgrade later. The frame, fork, Countervail seatpost, tire clearance, endurance geometry, and integrated storage are the reasons this bike matters. Those are not minor features. They define how the bike rides and why it is such a strong choice for long-distance road riders.

The 105 Di2 build is especially compelling because it gives you electronic shifting at a price that still leaves room for future upgrades. You can ride the included Bianchi B 30R alloy wheels confidently for training, rough roads, winter miles, and everyday use. Later, if you want a lighter or faster wheelset, the frame is already worthy of that upgrade. This makes the Infinito 105 Di2 one of the most practical ways to buy into Bianchi's newest endurance platform.

Best For: Endurance Road, Rough Pavement, Long Rides, and Light All-Road Routes

The Bianchi Infinito 105 Di2 is ideal for cyclists who want one bike for long training rides, century rides, fondos, fast weekend group rides, rough chipseal, broken pavement, and occasional light mixed-surface routes. It is a road bike first, but the combination of endurance geometry and wide tire clearance makes it much more versatile than a traditional narrow-tire race bike.

This is not the bike for someone who only wants a pure aero race machine or the lightest possible climbing bike. It is for riders who want speed with comfort, electronic shifting with value, and a premium carbon frame that can be ridden hard in real-world conditions. If your riding includes rough shoulders, back roads, long climbs, rolling terrain, and days where comfort matters as much as speed, the Infinito belongs on your shortlist.

2026 Bianchi Infinito Frame: Same Core Platform as Higher Builds

The biggest reason to choose this bike is the frame. The 2026 Infinito carbon chassis and fork bring a more modern interpretation of endurance road performance. Compared with the previous Infinito, the updated platform is built around improved aerodynamic efficiency, a more comfortable long-distance fit, greater stability, wider tire capability, and practical onboard storage.

Bianchi's design gives the bike a taller stack for a more sustainable riding position, longer chainstays for stability at speed, and clearance for tires up to 700x40. That makes the Infinito a strong fit for riders who want a fast road bike but do not want to be limited to narrow tires or aggressive race geometry. The hidden down tube compartment adds practical storage for a multi-tool, compact wind jacket, or small ride essentials, which is especially useful for long days and self-supported routes.

Countervail Seatpost Comfort System

The Countervail Vibration Cancelling System is one of the defining technologies of the new Infinito. On this model, Countervail is integrated into a full carbon aero-flex seatpost using Bianchi's updated viscoelastic material. The goal is to reduce vibration at a key contact point while preserving frame stiffness and road feel.

This comfort system matters for riders who spend hours on rough pavement, chipseal, patched roads, and mixed surfaces. Less vibration can mean less fatigue, better control, and a fresher feeling late in a ride. Smaller sizes use a 320 mm zero-offset seatpost configuration for 47-55cm bikes, while 57-61cm sizes use a 380 mm seatpost with -20 mm offset. That fit-specific approach helps the bike maintain proper rider position across the size range.

Shimano 105 Di2: Electronic Shifting Without the Premium Price Penalty

Shimano 105 Di2 is the drivetrain that makes this build so appealing. It brings electronic shifting to a more accessible price point while delivering the clean, consistent, repeatable shift feel that riders expect from Di2. There are no shift cables to stretch, no barrel-adjuster tuning to chase, and no compromise in day-to-day shift consistency.

This build uses Shimano 105 Di2 R7150 front and rear derailleurs, Shimano 105 Di2 R7170 hydraulic disc brake levers and calipers, a Shimano 105 R7100 50/34 crankset, and an 11-36 cassette. That gives the bike a practical gear range for sustained climbs, rolling terrain, mixed road surfaces, and endurance riding. The Di2 architecture uses a seatpost-integrated battery, and while this build does not include a power meter, one can be added later with a pedal-based or crank-based system.

Wheels and Tires: Durable Now, Upgrade-Ready Later

The Bianchi B 30R alloy wheels are a practical and durable choice for the Infinito 105 Di2. They are well suited for training miles, rough roads, imperfect pavement, and riders who want reliable wheels that can handle everyday conditions. Alloy wheels also make sense for riders who deal with winter roads, grit, road debris, potholes, or travel conditions where expensive carbon wheels may not be the first choice.

The Pirelli P7 Sport 700x35 tires give the bike comfort, control, and real-world capability out of the box. A 35 mm tire width works well for long-distance endurance riding because it adds volume and grip without taking the bike out of the road category. Since the frame supports up to 700x40, riders can go wider later for even more comfort and mixed-surface capability, or upgrade to a faster tubeless road tire setup depending on their priorities.

Who Should Buy the Bianchi Infinito 105 Di2?

This bike is for the rider asking: what is the best carbon endurance road bike with Shimano 105 Di2? What road bike can handle rough pavement and wider tires? What Bianchi road bike should I buy for long rides? What bike gives me electronic shifting, comfort, and upgrade potential without jumping to an Ultegra Di2 price?

The Infinito 105 Di2 is a strong choice for riders upgrading from an aluminum road bike, an older carbon road bike, or a mechanical drivetrain. It is also a smart choice for riders who want a new endurance bike that can keep up on fast group rides while staying comfortable on long-distance routes. If you value the frame first and see wheels as an upgrade path, this is one of the most logical builds in the Infinito lineup.

Why Choose This Bike Over a Pure Race Bike?

A pure race bike usually prioritizes low weight, maximum stiffness, or aerodynamic posture above all else. The Infinito takes a more practical approach. It still feels like a performance road bike, but it gives riders a more sustainable position, more tire clearance, more vibration control, and more stability over imperfect roads.

For most non-professional riders, that balance can make the bike faster over the whole ride. A bike that keeps you fresher, more comfortable, and more confident on real roads can be the better choice for long days, mixed conditions, and routes where pavement quality changes constantly.

105 Di2 vs Mechanical 105 vs Ultegra Di2

For most riders, the 105 Di2 build is the sweet spot. Mechanical 105 saves money, but it does not give you electronic shifting. Ultegra Di2 is more premium, but it costs more. The Infinito 105 Di2 sits in the middle with the features many riders actually want: electronic shifting, hydraulic braking, endurance comfort, wide tire clearance, and a premium carbon frame.

Why This Build Makes Sense

The Infinito 105 Di2 makes sense because it puts the money where it matters most: the frame, the comfort system, the electronic drivetrain, and the long-term upgrade platform. The alloy wheels and training tires are not a problem. They are durable, practical, and appropriate for the type of riding this bike is likely to see.

If you are the rider who wants carbon wheels immediately, the Pro build may be worth comparing. But if you would rather start with the same core Infinito chassis and upgrade wheels later, this 105 Di2 build is the better value. You get the electronic drivetrain now, the frame you want long term, and the freedom to build the bike further over time.
